According to CAR 302.31(3) "Compliance with Air Traffic Control Instructions and Clearances"
The pilot-in-command of an aircraft may deviate from an air traffic control clearance or an air traffic control instruction to the extent necessary to carry out a collision avoidance manoeuvre, if the manoeuvre is carried out
(a) in accordance with a resolution advisory generated by an ACAS; or
(b) in response to an alert from a TAWS or a Ground Proximity Warning System (GPWS).
I know that even in controlled airspace with separation/conflict resolution, and without equipment mentioned in (a) and (b) it is the responsibility of the pilot to avoid collisions. Is that covered by a different CAR?
